My monoblocks

Here they are: a couple after small ecl86 monoblocks and a matched Matisse - clone pre phono.

300B amp

Happy New Year everyone! These holidays have finally allowed me to finish my latest amp creation.

Very simple design - single input/driver stage using C3o tube (6.3V version of C3m), cap-coupled to 300B. I'm using permalloy Tamura iron and a Jensen silver foil coupling cap. I'm also using some new heater circuits (Rod Coleman design) which are really quite novel.

Sound is excellent. Very nice transparency, even better than my 3-stage designs. Fine details are unbelievable... a little better than my big 845 amp if I can be honest. Not quite the ultimate transparency of the 845 though.

I also built a 300B amp but with TJ Full music carbon plates and a 6SN7 driver. I love it and are playing right now. I also just finished a preamp using C3m tubes which is excellent. Do you have a schematic ?
